Automator Watermark PDF Workflow

Used Hiroto's updated Python script. Used the Waternark.png that you posted. Used your corrected command-line settings. There is no watermark produced, and the len(args) returns 1.

I tried Hiroto's small shell script with its args unchanged except for my input and output filenames. Like above, it runs ok, and there is no watermark on the output PDF.

Can I say frustrated?

When one formally designates the import items used in the code, instead of the more convenient splat, it runs in an eyeblink. Afterwards, 179 page PDF takes 1.8 seconds to watermark. Splat notwithstanding, this is another exemplary piece of code from Hiroto, and deserves a substantial "Thank you."

Well Tony, this PyObjC code is a work in progress. I cleaned up all syntax issues, but:

• The expected stamp file is hardcoded into the application, not up top as a constant.

  Replace confidential.pdf with your document (expects text on transparent background)

• Apparently, one must intuitively know the rect content setting
• The stamp is applied backwards \, not in the expected / orientation
• Syntax: ConfidentialStamper.py Lorem.pdf

  Output: Lorem.watermarked.pdf

Hi!

Thanks to Tony T1 & Hiroto first - great work guys!

I'm used this with previous OSX versions and now under 10.10 it's broken. So I managed to read through these topics here. What I've done so far:

Created a new folder on my desktop which should contain the neccessary files. I downloaded the tool.py from this topic - chmod'ed it and it works within command line:

./tool.py -h

['./tool.py', '-h']

Usage: watermark --input <file> --output <file> <watermark files>...

Using the tool.py manually works great as well:

./tool.py --under --xOffset 30 --yOffset 60 --angle 0 --scale 0.24 --opacity 1 --input test.pdf --output output.PDF vorlage.png

['./tool.py', '--under', '--xOffset', '30', '--yOffset', '60', '--angle', '0', '--scale', '0.24', '--opacity', '1', '--input', 'test.pdf', '--output', 'output.PDF', 'vorlage.png']

--under

watermark under PDF

--xOffset 30

--yOffset 60

--angle 0

--scale 0.24

--opacity 1

--input test.pdf

--output output.PDF

Here it is: http://pastebin.com/WyUPdh7x

Now I created an automator action based on Tony T1's - "Ask for finder objects" - "filter finder objects" - "execute shell sctipt" - it's all in german for me.

Unfortunately I get the error on line 8. I already removed every space after the "\" and I already tried to put everything into one line - no success at all.

Any idea about this?

Line 8 is the input one. I already replaced that one completely with one from another quote here... no success so far.

Ideas? Thanks a lot!

Hello

Here's sample pybojc code to draw text watermark using Core Text CTLine as a proof of concept.

#!/usr/bin/python # coding: utf-8 import math from Quartz.CoreGraphics import * from CoreText import * def drawWatermarkText(ctx, line, xOffset, yOffset, angle, scale, opacity): # CGContextRef ctx # CTLineRef line # float xOffset, yOffset, angle ([degree]), scale, opacity ([0.0, 1.0]) if line: rect = CTLineGetImageBounds(line, ctx) imageWidth = rect.size.width imageHeight = rect.size.height CGContextSaveGState(ctx) CGContextSetAlpha(ctx, opacity) CGContextTranslateCTM(ctx, xOffset, yOffset) CGContextScaleCTM(ctx, scale, scale) CGContextTranslateCTM(ctx, imageWidth / 2, imageHeight / 2) CGContextRotateCTM(ctx, angle * math.pi / 180) CGContextTranslateCTM(ctx, -imageWidth / 2, -imageHeight / 2) CGContextSetTextPosition(ctx, 0.0, 0.0); CTLineDraw(line, ctx); CGContextRestoreGState(ctx) # parameters ifile = 'input.pdf' ofile = 'output.pdf' text = 'Watermark Sample' xOffset, yOffset, angle, scale, opacity = 0.0, 400.0, 60.0, 2.0, 0.2 # create CoreText line (CTLine) font = CTFontCreateWithName('Helvetica', 36.0, None) astr = CFAttributedStringCreate(kCFAllocatorDefault, text, { kCTFontAttributeName : font }) line = CTLineCreateWithAttributedString(astr) # create output pdf context ourl = CFURLCreateFromFileSystemRepresentation(kCFAllocatorDefault, ofile, len(ofile), False) ctx = CGPDFContextCreateWithURL(ourl, None, None) # create input pdf document iurl = CFURLCreateFromFileSystemRepresentation(kCFAllocatorDefault, ifile, len(ifile), False) pdf = CGPDFDocumentCreateWithURL(iurl) if pdf: for i in range(0, CGPDFDocumentGetNumberOfPages(pdf)): page = CGPDFDocumentGetPage(pdf, i + 1) if page: mbox = CGPDFPageGetBoxRect(page, kCGPDFMediaBox) if CGRectIsEmpty(mbox): mbox = None CGContextBeginPage(ctx, mbox) CGContextDrawPDFPage(ctx, page) # elementary test CGContextSetTextPosition(ctx, 10.0, 10.0) CTLineDraw(line, ctx) # using general function drawWatermarkText(ctx, line, xOffset, yOffset, angle, scale, opacity) CGContextEndPage(ctx) del pdf CGPDFContextClose(ctx) del ctx

Briefly tested with pybojc 2.2b3 and python 2.6.1 under OS X 10.6.8.

Good luck,

Frank,

The tool.py file had a ton of Python syntax noise that I cleaned up. When I run it in the Terminal following precisely its command-line argument order, there appears to remain a consistent problem on line 31 with one of the Core Graphics methods, and a variable that was referenced before set. Will have to spend more cross-checking with the Dev docs. Maybe I can fix it.

I was trying to get the Python bit to work, because a UNIX executable living in MacOS that may also be a contributing factor to this misadventure.

Another interesting quirk with the workflow in Yosemite is that when you add the Watermark PDF Documents action to the workflow, in Mavericks the gray box to the left of the adjustments is filled with a pdf document from the actions resource folder, Bears.pdf, to enable you see what the watermark will look like. In Yosemite that dummy file is not loaded.

In my case, I want to get rid of the original file and replace it with a watermarked file with the same filename. This can be done with the following AppleScript. You don't need to "Dispense Items Incrementally" with this. Note I am moving the original file to an arbitrary folder called trashFolder.

It appears that this is the python script that the Automater Actions runs

/System/Library/Automator/Watermark PDF Documents.action/Contents/Resources/tool.py

and according to the error I get from Automator

It appears the script is throwing an error. Not a python scriptor but one of you might be bale to see what trouble is.

I am learning more about this Python code. The correct command-line input for Hiroto's patch that does not produce any Python errors:

odin: ~$ tool2.py --angle 0.45 --over --input Lorem.pdf --output LoremD.pdf Draft.png
['./tool2.py', '--angle', '0.45', '--over', '--input', 'Lorem.pdf', '--output', 'LoremD.pdf', 'Draft.png']
--angle 0.45
--over 
watermark over PDF
--input Lorem.pdf
--output LoremD.pdf

An output PDF is written — and silently ignores the Draft.png file — so there is no watermark applied.
